wuchong opened a new pull request #8695: [FLINK-12805][FLINK-12808][FLINK-12809][table-api] Introduce PartitionableTableSource and PartitionableTableSink and OverwritableTableSink URL: https://github.com/apache/flink/pull/8695 ## What is the purpose of the change Introduce `PartitionableTableSource` for partition pruning, and introduce `OverwritableTableSink` for supporting insert overwrite, and introduce `PartitionableTableSink` for support writing data into partitions. All of them are only supported in Blink planner in the first version. ## Brief change log This pull request only contains the three interface. We didn't include any implementations because: - `OverwritableTableSink` depends on the `INSERT OVERWRITE` syntax. - `PartitionableTableSink` depends on the `INSERT PARTITION` syntax. - `PartitionableTableSource` depends on the filter pushdown optimization implementation in Blink planner. ## Verifying this change N/A ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
